ASD Seminar Series

The goal of this seminar is to encourage interaction between groups, act as an open forum to share ideas, achievements, and results, promote collaboration, communicate what APS personnel are doing and to educate people. Talks can be projects, tasks, ideas, etc. that are new, unfinished, ongoing as well as fully developed. This seminar is very informal and does not require a fully formatted presentation.

To suggest a speaker or to volunteer, please contact Geoff Waldschmidt

Next Seminar: Friday, September 19 @ 9:00 am, Conf. Rm. A1100
TITLE: Wide Bandgap (WBG) Semiconductor Power Devices for Switching and RF Power Supplies
SPEAKER: Krishna Shenai, Energy Systems Division
ABSTRACT:

For nearly five decades, silicon has remained as the industry workhorse for solid-state electrical power switching and amplification. In the past three decades, there has been a concerted effort to develop Silicon Carbide (SiC) and Gallium Nitride (GaN) power semiconductor switching devices because of their potential for superior electrical and thermal performances compared to silicon power devices. This talk will discuss the current status and future trends in Wide Band Gap (WBG) power devices for switching and RF power supplies.
